HORlZONTALLY-PIVOTED WINDOW.

SPECIFICATION forming part of Letters Patent No. 760,140, dated May 17,1904.

A li ation fil d February 23, 1904:. Serial No. 194,75'7. (N0 model.)

To all whom it may concern:

Be it known that I, J osErH ELMER MoGnv- NESS, a citizen of the UnitedStates, residing at Pittsburg, in the county of Allegheny and State ofPennsylvania, have invented a new and useful Improvement inHorizontally-Pivoted Windows, of which the following is a specification.

The invention relates to windows having the sash horizontally pivoted tostrips on each side, which strips are adapted to be separated laterallyfrom the sash and to travel longitudinally in the grooves of thewindow-frame; and the object of the improvement is to provide a simplepivotal connection between the sash and the strip by means of which thesash can be stopped or held in various positions of rotation. Thisobject is attained by the arrangement, construction, and mechanismillustrated in the accompanying drawings, in which Figure 1 is afragmentary side view of a window frame and sash, showing the pivotalconnection in longitudinal section; Fig. 2, an enlarged longitudinalsection of the pivotal parts in the strip with the sash rotated to showa cross-section of the pivotal parts therein; Fig. 3, a cross-section ofthe frame and sash on line 3 3, Fig. 1; Fig. 4, a detached perspectiveView of the swivel; Fig. 5, a detached perspective view of thesash-plate; Fig. 6, a detached perspective view of the strip-plate; Fig.7, a detached perspective view of the spiral spring; Fig. 8, a detachedperspective view of the washer, and Fig. 9 a detached perspective viewof the swivel-pin.

Similar numerals refer to similar throughout the drawings.

The window-frame l is made in the usual manner with a groove 2 on eachside for'receiving the respective sash-strips. The sash 3 is made lessin width than the inside clear width of the frame, and the usual strips,as 4:, are pivoted on the side edges of the sash and are adapted tooperate in the respective framegrooves. The adjoining faces 5 and 6 ofthe parts sash edge and side strip are provided with grooves 5 and 6 andridges 5 and 6 having inclined sides, so that when thesash and stripsare alined and brought together the respective ridges enter and fit intothe corresponding grooves, as shown particularly in Fig. 3, and when thesash is rotated on the strips the ridges are forced out of the groovesand bear against the crests of the opposing ridges, thus sepa rating thestrips from the sash according to the depth of the grooves, as shown inFig. 2.

Each pivotal connection is composed of the sash-plate 7 the strip-plate8, the swivel 9, the swivel-pin 10, the spring 11, and, preferably, thewasher 12 and is best located in the transverse axis of the sash. Thesash-plate 7 is countersunk in the side edge of the sash,where it isattached, as by the screws 13. The face of the sash-plate is grooved andridged like the edge of the sash and on the rear side is provided theswivel-hub 14, in which is found the axial swivel-bearing 142. Acrossthe rear end of this hub are provided the series of ribs 15, which havethe inclined sides 16 and are preferably radially located, as shown. Infront of the swivel-bearing and extending to the face of the sash-plateis provided the somewhat larger and likewise axial main bearing 17 ofthe pivotal connection.

The strip-plate 8 is countersunk in thesash side of the strip, where itis attached, as by the screws 18. The face of the strip plate is groovedand ridged like the side strip, and on the same side is preferablyprovided the pivothub 19, in which is provided the axial swivelaperture20, and which hub is adapted to enter endwise and rotate in themainbearing of the sash-plate. The rear part of the swivelaperture issomewhat enlarged to form the socket 21 with the annular shoulder orseat 22 for the spiral spring 11, and on the rear side of thestrip-plate are provided the lugs23on 1 each side of the spring-socket,between which lugs are formed the diametrically opposite guid e-slots24, in which the ends of the swivelpin 10 are adapted to operate. Theswivel 9 comprises the shank 25, having the transverse hole 26 in oneend for the pinlO' and the head 27 on the other end, across the innerfaceof which head are provided the grooves 28, preferably with inclinedsides, which grooves cor respond in location and arrangement with ribson the rear end of the swivel-hub of the sash-plate. The parts of thepivotal connection are assocket.

sembled by bringing the grooved and ridged faces of the sash and stripplates together, with the ridges of the one entered in the grooves ofthe other and with the pivot-hub of the strip-plate entered in the mainbearing of the sash-plate, and the shank of the swivel is then enteredthrough the swivel-bearing of the sash-plate and the axial aperture ofthe strip-plate to bring the ribs on the sash-plate hub into the grooveson the swivel-head, after which the spiral spring is placed around the.

swivel-shank against its seat in the strip-plate The washer is placedaround the swivel-shank against the spiral spring,- and the swivel-pinis entered through the hole' in the end of the swivel -shank, withitsside against the washer and its ends in the guideslots between the lugson the strip-plate, in which normal relation of the parts thespiralspring is so confined or compressed that its energy acts to prevent aseparation of the sash-plate from the strip -plate and of theswivel-head from the sash-plate hub.

With the parts of the pivotal connection thus assembled and therespective plates attached to the sash and the strip, one on each sideof the window, and with the strips entered in the window frame groovesthe sash is adapted to be rotated on its horizontal pivots by merelypulling or pushing the upper or lower end of the sash. In such rotationthe side strips are of course separated from the edges of the sashin'the usual manner by the action of the inclined sides of the ridges onthe one against the similar inclined sides on theother until the crestsof the ridges of the one ride on the crests of the ridges of the other,as shown in Fig. 2, and the endwise movement of the swivel-shank in theaxial aperture of the strip-plate necessary to accommodate thisseparation is permitted by the movement of the swivel-pin in theguide-slots between the lugs on the strip-plate to the position shown byfull lines in Fig. 2, and as the swivel is held against rotation by theswivel-pin in the guide-slots the rotation of the sash also acts toseparate the swivel-head from the sash-plate hub, which is accomplishedby the action'of the inclined sides of the hubribs against the inclinedsides of the head.- grooves and the endwise movement of the swivel-shankin the swivel-bearing of the sashplate, and the additional movement inthe axial aperture of the strip-plate necessary to accommodate thisseparation is permitted by the further movement of the swivel-pin in theguide-slots to the position shown by broken lines in Fig. 2. When theswivel-head is thus separated from the sash-plate hub, the hubribs rideon the adjoining faces 29 of the head between the grooves until the ribsregister with the next grooves, whereupon the action tion until the ribsare again forced out of the grooves, as before described, and in thesame manner the sash can be rotated and stopped at various points.

When the sash and strips are alined, their edge grooves and ridges, aswell as the ribs and grooves on the sash-plate hub and swivel-head, actto stop the sash against rotation; but when the sash is turned out ofline with the strips the latter ribs and grooves act alone to thisefiect, and in this latter action the swivel has an endwise movementindependent of and in addition to the endwise movement caused by theseparation of the strips from the sash. WVhile the sash is described asbearing both on the swivel and on the pivot-hub, either one or the otherof these hearings can be used as a principal hearing; but it ispreferred to make the main bearing on the pivot-hub, because of thegreater freedom thus given to the swivel for its endwise movements.

What I claim as my invention, and desire to secure by Letters Patent, is

1. In combination, a window-sash and a separable strip on its side edge,there being corresponding grooves and ridges on the adjoining faces, anda pivotal connection between the sash and the strip comprising apivot-hub with an axial aperture on the one, a non-rotatableendwisesmovable swivel in the aperture having, a head with groovesacross its inner face, a bearing in the other adapted to operate on thepivot-hub having .ribs with inclined sides on its end adapted to enterthe head grooves, and a spring acting to move the swivel-head toward thepivot-hub.
